I want to know how much you pay for installing solar panel?
Depends, see http://www.affordable-solar.com/ as a starting point. I noticed that they don’t always list the best panels (best performance/cost ratio – measured as $ per watt) though. First Solar’s production cost is about $0.89/watt – don’t know what they charge, Sun Power’s arrays cost nearly $2.50/watt.. but their is a second difference, First Solar has about 11% efficiency of conversion while Sun Power’s is about 23%.. so fewer panels are needed and less mounting hardware, roof/surface area etc.
from which company?
again, see website above.
The energy generated from solar panel can cover your full electricity bill?
depends upon installation.. Some people go for overkill… http://www.solarwarrior.com/ This one supplies enough to recharge the guy’s electric cars and he has a battery backup with storage close to 1 week of consumption.. and still makes his house a net provider. .. though it would take almost 2 of his systems to offset Al Gore’s consumption. There is also a San Diego ‘group’ that tracks their production – http://www.livesolar.net/ – please don’t everybody jump there and crash their server.
